Abnormal NT scan ?!

Hey ladies I had a NT scan with a Result of 3.4 . Doctor said anything over 3 is considered high risk for chromosome abnormalities.. blood work cake back a little high to . He wanted to wait two more weeks in order to do the NIPS test. I’m losing my mind . This is our rainbow baby.. has there been anyone out there that has gone through this and baby came out healthy 😣❤️ . I’m only 21 so I don’t think my age would have anything to do with it .
